WTB -72 402 smog tubes
Looking for a drivers side set of smog (A.I.R injection ) tubes. Would buy a pair . The attached photo doesn't show the whole thing but it is the clearest pic I have of one. Any help would be appreciated. I am told there are people that can repair these if the end fittings are twisted off?? Thanks Chuck
The second photo is a passenger side. It is the same except the inlet is angled forward instead of vertical like the drivers side. Last edited by 72BBChuck; 04-10-2022 at 11:56 AM. Reason: added more info |

Re: WTB -72 402 smog tubes
I have these these . Left part number is 14050537 no part number on the the rh one . These were hard to find back in the 90s when I bought them . They look like later big block tubes but should work .
$400 shipped

Re: WTB -72 402 smog tubes
Thank you Larry for the EBAY links. I had searched there but not found either of the ones you pointed out. The 72 Corvette RH looks the same as a truck but the part # doesn't match??
Thank you 72c20customcamper for your offer. I think you are correct. These GM tubes seem to match the generic 454 replacement tubes made by Standard Motor Products and offered by Summit Racing or Amazon for about $84 per side. They are my plan B. I do have a nice set of small block "antlers" and, I think, all the other SMOG components for a small block if anyone wanted to do some trading. Thanks again guys, Chuck |

Re: WTB -72 402 smog tubes
Thanks for the help Larry. I went ahead and bought the one you linked to ebay and the mate for the other side. The big block smog tubes seem to be real tough to come by as they appear to only have been used on 72 C-10 with 402 and earlier big blocks with California emission control. I will keep looking the correct truck LH but the prospects seem slim. Chuck
